upon the unciform axes. Seven or eight species 1 of this genus are 

 known, principally natives of the warmest regions of Asia and 

 Malaysia. One or two species inhabit tropical Western Africa. 



III. LOPHIRA SERIES. 



Lop/iira' 2 (figs. 217-221) has regular hermaphrodite flowers. Upon 

 the narrow flat receptacle is inserted a subhypogynous perianth, 

 composed of five sepals, subequal, free, or nearly so, and quin- 



Lophira alata.

cuncially imbricated, and of five alternate petals, contorted or 

 imbricated in the bud. The androceum is formed of a very con- 

 siderable number of stamens. The filaments are free except at the 

 base, and surmounted by an anther with two equal linear cells, 

 introrse and dehiscing longitudinally. 3 The gynseceum is free ; it is 

 formed of a one-celled 4 conical ovary, terminated by a style with two

 which has caused it to he possible at a certain 

 age to consider theua as pores. 



4 There are found, it is true, two parietal 

 rudiments of vertical partitions corresponding on 

 each side to the interval of two neighbouring 

 series of ovules; but they are little prominent 

 in the cavity of the ovary. Nevertheless, with 

 the two branches of the style, they would seem 

 to show that the gyna;ceum is really dicar- 

 pellary.
